Congenital Anamolies Prevalence in Routine Antenatal Ultrasound

Objectives: To assess the antennatal prevalence of significant congenital anomalies.

Study Design: To evaluate the incidence of important lcongenitallanomalies in the antenna. Setting: Department of Radiology, Sree Balaji Medical College and Hospital, Chrompet, Chennai. Duration: 19 months from March 2017 to September 2018. Sample size: 2839.

Material and Method: Review assessment of lallantennatal patients undergoing obstetric ultrasound was performed. During the course of the study, obstetric ultrasound tests were conducted for 2839 lpatients. In order to identify the incidence of lcongenital anomalies, lData was evaluated from all antenatalllultrasound examinations. LData was placed in the Excel ldata sheet and the suitable data analysis was carried out.

Results: 55 instances of birth defects were identified. The incidence of antennatal anomalies was 19.43 per 1000 and 1.9 per cent. The median maternal angel at diagnosis was 26.7 lyears. The average gestation at diagnosis was 21 weeks+/-three days. The most frequent were Central nervous system, cardiovascular and gastrointestinal lanomalies. Conclusion: The incidence of important congenital lanomalies in population studies was 1.9%. Brainstem malfunctions were most prevalent, preceded by cardiovascular and urogenital system malfunctions.
